Hey Guys,

I just bought a totally stock 89 and frankly the engine sounds like a sick, raspy, sewing machine. I've never had a Blaster with the stock exhaust before so I've never had one this quiet. Is it really supposed to whir and click so much? I def hear the reeds but there is a lot of other noise too.

The funny thing is it runs like a champ. Plenty of power, etc. Whaddya think?
 
OK Guys. Thanks, that's about what I thought it should sound like. Mine sounds MUCH worse. I'm thinking bearings but I'm surprised it runs so well since you'd think rings would go out before bearings.
 
Ok, well I decided to just tear it apart. I kinda wish I had recorded it first, it was kinda funny.

It ended up having bad crank bearings. Makes noise even turning it by hand (with the jug off). I didn't know they could be that bad without seizing. There was also alot of play in the rod bearings so maybe it had a knock too. I also comp tested it - 65lbs. Still ran like a raped ape, all things considered. Just shows you what a tough design those old motors are.

Luckily, when I bought it, it came with a box o' parts including another motor! I combined parts from both and after shaving the head a bit I put it back together. Hopefully I can start it tonight!
